The slate crenate loves very bright positions, possibly even in full sun; in summer it can be taken outside, in the garden or on the terrace of the house, taking care to shade it on hot days too intense that could cause the yellowing of the leaves; in winter it is sheltered in the house, possibly near a window to allow the plant to grow at its best. The ideal climate for this plant is around 20°C, excessively low or excessively high temperatures cause the fall of fruits and leaves.
- To the genus ardisia belong hundreds of plants, spread in most of the tropical areas of the globe; in reality, in the nursery we find almost exclusively Ardisia crenata, a species native to the world of…
Watering of the slate must be regular from April to September, between one watering and another, the soil must dry on the surface, while remaining a little wet. In winter, thin out the watering a little, taking care, however, to vaporize the leaves often with distilled water. From April until the berries turn red, add universal fertilizer to the water every 10-12 days.
The ideal soil for growing Crenate ardisia is composed of peat, sand and soil in equal parts. Since this plant needs frequent watering, it is advisable to cultivate it in a very well drained soil, to avoid dangerous water stagnations; if desired, we can add coarse-grained material on the bottom of the pot, to improve drainage.
To reproduce our a.crenata, we must sow in spring at a depth of five millimetres in fertile, moist soil at 24 degrees centigrade. When the shoots appear, the temperature must be lowered to 15 degrees. For cutting, we take, from May to August, the seven-eight cm long portions from the lateral shoots, we plant them in a mixture of peat and sand in equal parts and we root them, then we transplant them after six-eight weeks.
The excessively tall plants can be pruned in February, the branches are cut at seven-eight cm from the base, when the cut no longer emits sap, the watering begins again to stimulate the plant to form new shoots. Among the new ramifications, only the most vigorous will be left, cutting the others.
Ardisia – Ardisia crenata: Pests and diseases
With regard to diseases and pests that could attack the plant, particular attention should be paid to aphids and cochineals. Green aphids attack young leaves and tender shoots; floury cochineals form white spots on ripe berries.
